Dummie’s guide to carrier steering and brake adjustment please

[Big D]

Gidday Lynn,

Yes, the view I have shown in the photograph is (via the mirror) looking back along the floor of the hull, through the bulkhead in the drivers area, looking back at the clevis on the camplate. You can make out the camplate in one of the two pictures I posted.

In the picture you have posted, it is the left side clevis mounted on the camplate (labelled J) that is the problem.

The problem is that once this clevis is fully back (toward the rear of the carrier) it drops below a plate that is bolted to the hull around the area where the cross shaft goes.

As you say, it is simply a little too close to the floor. I would say it would only need 1-2 mm shaved off the underside of that clevis (or off that plate) but the problem is getting too it, so I could remove the clevis mounting screw.

Does that help explain my predicament?

Cheers

I am guessing there may be a washer missing from under the bearing,or some other assembly fault, with your cam plate. The English/ Canadian carriers, have very little clearence for the bottom end of the clevis pins, but the Aust design allows more room, and hence have bigger dia. split pins, and longer ends to the clevis pins.
Your long clevis's are virtually rubbing on the floor.
Can one of you Aussie guys put up a parts breakdown for the cam plate, showing whats there is in the way of washers, spacers etc.
Ron, what you you tell us?

Thanks Lynn

Do you have any secrets for actually accessing the area?

Cheers

Im guessing that if you disconnect the brakes at the rear, then you can probably get full rotation of the cam plate. This in turn, may allow you better access to the pins in the long clevis's (j)

Hi Darryl &Lyn,
Lyn I think that you are correct, there is a washer missing from under the cam plate,and I would hazzaed a guess that The clevis pin is too long,and what you suggest regarding disconnecting the brake rods to test for movement is also the way to go,I think that I would also check to see if I was getting the same amount of movement in either direction of the cross shaft , Idealy I would remove the steering cam plate and give it a good check over, I realise that Darryls carrier has been rebuilt but the bearing might be buggered and not allowing enough movement,its not a big job and its best to look at all of the options,good luck Darryl keep us posted,
Regards to you both,Ron

Hi Ron and Lynn,

Thanks for the replies. I will give your suggestions a go and come back to you. My biggest problem is going to be squeezing into that little gap again!

Gidday Lynn and Ron (and anyone else),

Just wondering if I can get some more advice about how best to attack this problem I have.

No matter what I do I can’t seem to squeeze into the right rear crew area enough to get anywhere near the clevis holding screw on the left side.
I figure I have two options to deal with the problem:

1. I undo the castellated nut on the cam securing bolt and then remove the full inspection plate from underneath the hull. I’ve had ‘a play’ with this option already but unfortunately I am not dealing with simple bolt holes tapped into the hull. Some bots are secured by nuts on the inside of the hull, again in a very tight area to access.

I figure if I can remove the plate (correct me if I am wrong) this plate and the plate with the cam securing shaft will fall away leaving the cam still inside the hull and still secured to the steering column by the connecting rods and clevises.

Then, I find a suitable washer or some other spacer and fit it to the cam shaft and simply replace the assembly.

That should give the cam a couple of mm of lift which should mean the clevis will clear the metal plate it is currently striking.

Alternatively, I just remove the plate with the cam securing shaft and follow the same procedure above. I haven’t really looked hard at this option and from what I recall I will have to rotate the cam until I can access each of the four nuts so as to remove the four securing bolts.

Am I on the right track here?


2. I get a small suitably bladed grinder or something similar and after removing the driver’s seat I access the very small hole in the bulkhead and see if I can grind 1-2 mm off the plate on the hull just under where the left side clevis will slide.

I figure this will be a mission in itself and will be reliant on getting a suitable grinder or some other appropriate tool. It really needs to be about the size of a file but be able to take off the required couple of mm in that plate in a very confined space.

Any other thoughts on how I attack this?

Cheers

Darryl
